✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Numerical experiments in close-proximity operation scenarios demonstrate that the proposed pipeline achieves over 90% SCP convergence and yields a 1.5× higher rate of generating trajectories that satisfy the top intent-prioritized performance criteria than heuristic decision-making.

C2weakest assumption

That the intermediate abstractions of behavior sequences and waypoint constraints can reliably translate high-level intent predictions into constraints that preserve both safety and intent alignment during optimization.

C3one line summary

A pipeline links foundation-model intent reasoning to safe trajectory optimization via behavior sequences and waypoint constraints, achieving over 90% convergence and 1.5x better intent satisfaction in close-proximity tests.
